Tkme: Another editor for formal metadata

This page describes an editor for formal metadata, that is, structured documentation conforming to the Content Standard for Digital Geospatial Metadata developed by the Federal Geographic Data Committee (FGDC).

New! Tkme version 3 helps you select keywords using vocabulary web services.

The editor shares a considerable amount of its code with its progenitor, Xtme, which is specifically for Unix systems and is based on the Athena widget set of the standard X Window System distribution. Both Tkme and Xtme are closely allied with mp, a compiler for formal metadata, whose purpose is to verify that the syntactical structure of a file containing formal metadata conforms to the FGDC standard, and to re-express the metadata in various useful formats. The editors are intended to simplify the process of creating metadata that conform to the standard.

Tkme can be built for Unix systems if desired. Tkme is specifically designed as a port of Xtme to Microsoft Windows 95, 98, NT, and 2000.

The editor and the metadata compiler are both available in source and executable form through <>

Getting started

Linux users

Tkme can be compiled from the source distribution or it can be run as a tclkit. Download tkme.kit and an appropriate version 8.4 of Tclkit. Rename the tclkit and place in a convenient location such as /usr/local/bin/tclkit. Then run Tkme using the command tclkit tkme.kit


The formal metadata for xtme describes the editor and its usage. Generally what goes for Xtme goes for Tkme. In addition to menus a number of keyboard shortcuts are provided. Generally keystrokes involving the Alt key affect the structure of the metadata while keystrokes involving the Ctrl key affect the operation of the program.
